Dam Safety

The Maguga and Driekoppies Dams were constructed to meet the highest safety standards. Despite the very small likelihood of events occurring that could result in dam failure, KOBWA recognises and takes seriously the huge hazard that would be imposed onto human life, infrastructure and the environment should such failure occur. Therefore, the Dam Safety Unit ensures that the dams and reservoirs are operated and maintained safely to prevent dam failure. The Dam Safety Unit is responsible for conducting hazard inspections of the dams, repairing or modifying dam structures, as well as developing and exercising Emergency Preparedness and Action Plans to be used in the event of floods and dam failure. The Dam Safety Unit has a strong monitoring component. They observe, record and analyse data and report on the behaviour of the dam structures. Many instruments are placed in and around the dams to monitor seepage, pressure and movement characteristics. These are all indicators of structural integrity and provide early warning of possible failure.
